1) He has a real opportunity to transform the industry if he publishes his grading criteria. I can see why CGC hasn't, but it's a real weakness that could be exploited by a competitor. By doing so, he has a chance at becoming the "industry standard." The Overstreet criteria has always been too vague and conflicting, and CGC has always been proprietary and fickle. If he establishes transparency, he could end up being the yardstick which everything is compared - not a bad position for a new competitor.
